Effect of salinity, alkalinity, phosphate and organic matter on the movement of nematicides in soil

There are many problems associated with the application of pesticides in the soil, as reviewed by Bailey and White (1970). Singh et al. (1977) found that several factors such as organic matter, calcium carbonate and pH of the soil influenced the movement of nematicides. No attempt has so far been made to determine the effect of different salts, normally present in the soil, on the mobility of nematicides. The present study examines the effect of different saline, alkaline, phosphatic and neutral salts on the movement of dazomet, ox amyl and dichlorofenthion in the soil.
